The material of FRP.PVC/FRP and PP/FRP tower equipment is supplied by the qualified sub-suppliers from abroad and domestic,all of them certified by ISO9001:2008 Quality System is the fundamental requirement. The selection of material can meet the requirement of corrosion resistance;through the finite element analysis can change the structure and improve the strength of the laminate, to meet the requirement of the relative temperature and pressure. The fabrication,inspection and acceptance of PVC inner layer.PP innerlayer,PVDF inner layer and the fittings are carried out the standard of HG20640-1997 Plastics Equipment;the external reinforcement then be executed the standard of JC/T 587-1995 Filament Wound Reinforced Plastics Tank strictly.
